. formed and upon each line feed operation a feeler 11 Claims.

This invention relates to printing telegraph apparatus and more particularly to automatic paper feeding mechanisms therefor.

The principal object of the present invention is to provide in a line feeding mechanism responsive to code combinations of signal impulses, a means for efiecting automatically a variable additional number of consecutive line feed operations under the control of the record strip.

Another object of the invention is to provide an all mechanical means controlled solely by a single designation in the record strip for interrupting previously initiated consecutive operations of the line feeding mechanism of a printing .telegraph machine.

i the function bail, and restore the stop gate to its When using record material comprising a series of blank forms of the same standard length and having preprinted headings, it is desirable to provide in page printers, mechanism for exercising control over the proper feeding of the forms into printing position. The messages on each form, of course, may contain different numbers of recorded lines, and accordingly, before the first .line of the next message may be printed, an additional feed must be imparted to the preceding message in order to bring the next Patent 1,904,164, and for achieving the object of the invention, a special signal, which will be identified herein as the vertical tabulator signal, controls the selection of a special function lever, which, when operated in response thereto, actuates a multi-armed lever, which in turn sets up four conditions; namely, first, a contact in the operating circuit for the start magnet of the transmitting distributor is opened to suspend transmission during vertical tabulatiom second, the multi-armed lever is latched in its actuated position, which condition is maintained during vertical tabulationg third, the line feed push bar is held in the path of the function bail; and fourth, the stop gate of the selecting unit is held released to permit continuous rotation of the selector cam assembly during vertical tabulation. While these four conditions are maintained, a succession of line feed operations is perstop position.

The foregoing and other objects of the invention will be apparent from the following description when taken in conjunction with the accompanying drawings, wherein like reference characters designate similar parts throughout the several views, and in which Fig. 1 is a perspective view of a mechanism according to the present invention, only so much i of the printing telegraph apparatus being shown as is necessary to an understanding of the invention;

Some of the novel features shown but not claimed herein are shown and claimed in the copending applications of Charles W. Burcky Serial No. 345,258 and of Raymond E. Zenner Serial No. 345,257.

Having reference particularly to Figs. 1 and 2, the mechanism according to the present invention is shown as embodied in a telegraph printing machine of the type disclosed in U. S. Patent No. 1,904,164, to which reference may be had for a detailed description of the printer elements. The selector mechanism is of the single magnet type and comprises a selector magnet ll (Fig. 2) which is responsive to code combinations of signaling impulses. The magnet H has an armature l2 to which is fixed a lever l3. Lever l3, at its end adjacent to armature I2, is supported upon the pivot stud I4. A spring l5 has one of its ends secured to armature l2 and its other end secured to an adjusting screw l6. Normally the magnet H is energized and holds the armature l2 attracted, against the pull of spring l5. The free end of lever |3 is provided with a pair of laterally extending arms or abutments I1 and I8, which co-operate with laterally projecting arms l9 and 2| on the rear ends of selector fingers or swords 22 to position the latter in their clockwise or counterclockwiseposition, as will presently appear.

Power for operating the selecting mechanism is supplied by a motor (not shown) to main shaft 23 (Fig. 1) of the printer. Mounted near one end of shaft 23 is a selector cam barrel 24, which is frictionally connected to shaft 23 by means of suitable clutch members. The cam barrel 24 is provided with a helically arranged series of cams 25, one for each element of the permutation code. The series of cams 25-co-operate with a corresponding series of bell crank levers 26, pivoted on a common shaft 27 and normally biased clockwise (Fig. 2) by individual springs 28. Intermediate the arms I9 and 2| of swords 22 is a circular portion 29 adapted to fit into corresponding sockets in bell crank levers 26. By the action of cams 25 on bell crank levers 26, swords 22 are caused to thrust successively longitudinally of their lengths as the cam barrel 24 is rotated. In addition to this reciprocative movement, swords 22 have an oscillatory movement about circular portion 29 depending upon the co-operative relationship between abutting elements H and I9, and I8 and 2|. A friction holding means (not shown) is provided to hold the swords 22 in the position to which they have been set. The springs 28 associated with bell crank levers26 normally hold the swords 22 in their forward (rightward as viewed in Fig. 2) position and in engagement with a corresponding series of T-levers 3| pivoted at 32. Levers 3| are articulated to selector vanes 33, and rock said vanes to their clockwise or counterclockwise positions depending upon whether the swords strike them above or below the pivot shaft 32.

Selector lever I3 is also provided with an arm 34 terminating in an eccentrically headed adjustment screw 35, the function of which is to initiate, through a series of levers, the rotation of the selector cam barrel 24 in the following connection with constantly rotated shaft 23. Thus, stop disc 52, through its arm 5|, tends to rotate stop gate 46 in a counterclockwise direction against the action of spring 53, but this movement is resisted by a shoulder 54 on latch 4|. However, upon the receipt of a start or spacing signal impulse which is equivalent to an open line condition, the magnet II is de-energized and the selector arm or lever I3 is rotated clockwise (Fig. 2) under the action of spring l5. This causes the head of screw 35 to be actuated downwardly (as viewed in Fig. 2) to push plunger 36 correspondingly, thus imparting clockwise (Fig. 1) movement to bell crank 38, which causes latch 4| to rotate in a counterclockwise direction against the action of compression spring 43 sufficiently to withdraw shoulder 54 from cooperative engagement with arm 45. Stop gate 46 is free to respond to the greater. pressure imposed upon it by stop arm 5| which overcomes spring 53. Stop gate 46 is thus rotated by arm 5| until arm 49 has become disengaged from arm 5|, whereupon arm 5| and hence cam drum 24 continue to rotate during the ensuing cyclic period, and stop gate 46 is returned to its clockwise position (as viewed in Fig. 2) by spring 53. However, there is a slight overtravel of the stop gate 46 in its return movement, so that arm 45 will be moved clockwise sufficiently to permit the engagement of shoulders 54 and arm 45.

Upon receipt of a code combination of signal impulses, the start impulse serves to release armature l2, whereupon screw head 35 presses plunger 36 to effect, through levers 38 and 4|, the removal of shoulder 54 from arm 45 so that arm 5| overcomes stop gate 46 counterclockwise and the rotation of cam drum 24 is initiated. During the ensuing single revolution of cam drum 24 the cam portions 25 thereon act sequentially on levers 26 to draw swords 22 leftwardly (as viewed in Fig. 2) so that abutments l9 and 2| thrust against arms IT or l8, respectively, depending on whether lever I3 is in attracted or I released position in response to the marking or spacing signal impulses, respectively, in the code signal. Swords 22 under the action of springs 28 act upon levers 3| to set the selector vanes 33 corresponding to the code signal received by the selector magnet manner: Having reference to Fig. 2, it is observed 1 that the head of screw 35 strikes against a plunger 36 slidably carried in a support 31 to actuate a trip member in the form of a small bell crank lever 38 pivotally mounted on shaft 39 so that its opposite arm may engage one arm of a latch 4| pivoted at 42 in a support 43 (Fig. l). The extremity of the vertical arm of the bell crank 38 engages the latch 4| at a point coincident with the axial center of shaft 23 and of a pivot stud 44 which is employed for orientation purposes, as fully set forth in said aforementioned patent. Latch 4| co-operates with arm 45 of a U-shaped stop gate 46 rotatably mounted on a pivot 41. Latch H is normally held in co-operative engagement with arm 45 of the stop gate 46 by a compression spring 48 (Fig. 1). Arm 49 of stop gate 46 is adapted to be engaged by an arm 5| of stop disc 52 fixedly related to the cam barrel 24. Cam barrel 24 and stop disc 52 constantly tend to rotate (clockwise as viewed in Fig. 2) due to the frictional Associated with selector vanes 33 are a plurality of function levers, one of which is the vertical tabulator function lever 55. The function levers are pivotally mounted on a common shaft 56 and are provided with individual springs 51 which act upon selection to rotate said function levers clockwise (as viewed in Figs. 1 and 2) into co-operation with selector vanes 33. The function levers are held in their counterclockwise position by a rod 59 of a function lever bail, whose operation is controlled by the printing bail, as fully described in the aforementioned patent.

Function lever 55 is provided with a leftwardly extending arm 6| carrying at its extremity an adjustable striker screw 62 which co-operates with one arm 63 of a plural-armed lever 64 pivoted on shaft 69. Lever 64 is provided with an arm 65 which extends underneath the line feed push bar 66 (Fig. 1), and also a vertical arm 61 which terminates in a laterally disposed portion adapted to engage with a latch member 68 pivoted on rod 1|. Also pivoted on rod H is a U-shaped lever member 12 provided with a depending arm 73 and a horizontal arm 14. At the extremity of arm 13 there is pivoted the line 2,273,067" feed push rod 66 which is provided at its free end with a shoulder adapted to co-operate with the function bail blade 16, as described in the aforementioned patent. Arm I4 of lever 12 has pivotally secured thereto one end of a line feed link I7, the other end of which is pivoted to the horizontal arm of a line feed bell crank lever I8, pivoted at I9. At the end of the vertical arm of the bell crank lever I8 is pivotally carried a line feed pawl 8| which cooperates with a line feed ratchet wheel 82 secured to a cylindrical platen 83. 1

Plural-armed lever 64 has also an arm 84 which performs the dual purpose of controlling the vertical tabulation operation (multiple line feed) through the stop gate latch 4| (as will presently appear), and of opening the operating circuit of the start magnet of the transmitting distributor to suspend transmission during tabulation. Having reference to Fig. 1, the extremity of arm 84 of lever 64 overlies spring 85 of a normally closed contact 86, which is included in an obvious circuit for energizing a stop magnet 60 of a transmitter distributor, indicated generally by a dotted square I0, the transmitting contacts 80 of which are connected in a line wire 90 including the selector magnet II. Where operating conditions are encountered such that the speed of the motors are determined by governors, and the governed motors of the printers in the circuit run at slightly different speeds, a time delay relay may be introduced in the circuit for magnet 60 such as is shown in copending application Serial No. 345,258, filed July 13, 1940 by Charles W. Burcky, the purpose of which is to delay the resumption of transmission until the slowest printer in the circuit has completed vertical tabulation. Arm 84 overlies an arm 81 of a bell crank lever 88 pivoted at 89, the depending arm 9I of which is pivoted to a link 92. Link 92 is connected to depending portion 93 of a member 94 slidably carried on a rod 85. Member 95 is provided with an arm 96 which co-operates with the depending arm of bell crank lever 38 to effect under predetermined operating conditions the rocking of latch lever M to release the stop gate member 46 to permit the rotation of the stopodisc 52, and hence cam drum 24.

Latch member 68 has fixed thereto a stud 91 which fits into the lower forked end of a bar 98, the upper end of which is pivoted at 99 to the extremity of a lever IOI clamped to a pivot rod I02 carried by the printer frame. Fixed to link 11 is a member I03 having a laterally extending portion I04 positioned adjacent the lower side of lever IOI so as to impart rocking motion to lever MI in response to the reciprocating movement of link 71 during the line feeding operations. A lever I05 is fixed to shaft I02 at the end opposite to lever IM and is provided with arms I06, I01 and I08. To the extremityof arm I06 is attached one end of a spring I09, the other end of which is attached to a spring post II I carried on the side frame II 2 of the platen carriage. Arm I08 of lever I05 carries at its extremity a stud II3 which acts upon an arm II4 of a multi-armed lever II5 (as will presently appear) to rotate lever I I5 clockwise about its pivot I I6. Arm I 01 of lever I05 is provided at its extremity with a laterally directed portion which co-operates with an arm II! of lever H5. Lever II5 has also an arm IIB conformed at its extremity with a sensing portion or feeler H9 (Figs. 1, 3 and 4), the function of which is to sense or search for a control perforation in the record material or printed form. The feeler H9 is receivablein a groove I2I in the platen 83 to provide clearance for the movement of the feeler II9 when a control perforation is found.

A' guide member I22 is associated with the feeler II9 to facilitate the passage of the record material between said feeler and the platen 83. Guide I22 is provided with a notch or opening I23 to guide the feeler H9, and is-integrally united with a 'lever arm I24 freely mounted on pivot H6. Lever I24 is normally biased counterclockwise by a spring I25 to press the guide I22 against-the platen 83.

Lever II5 has also an arm I26 which terminates in a shoulder I21 which engages a latch arm I28 fixed to a rock shaft I29 to which a normal tendency to rotate in a counterclockwise direction is imparted by a spring I3I. Lever H5 is normally biased in a counterclockwise direction by a spring I 32 extending between a spring post secured to arm I26 and a spring post mounted on frame II2. Fixed to rock shaft I29 and in operative alignment with line feed bell crank lever I8 is an arm I33.

An arm I34 is freely mounted on rock shaft I29 adjacent the latch arm I28 and is pivotally articulated to one end of a link I35, the other end of which is pivoted to arm II8 of lever II5. A stud I36 is secured to link I35 and overlies arm I24 and acts, when link I35 is moved downwardly, to rotate arm I24 clockwise against the tension of spring 25 moving guide I22 away from the platen 83 to facilitate the placing of record material in the printing apparatus preparatory to printing. Simultaneously, link I35 in its downward movement and due to its pivotal articulation with arm I I8, rotates lever I I5 so as to bring feeler H8 out of contact with the record material as it is inserted between the platen and the guide I22. This downward movement of link I35 to facilitate the insertion of a new supply of record material is controlled by a cam portion I31 integral with a pressure roller lever I36 pivoted at I39 to the platen carriage frame II2. Lever I38 is normally spring biased by a spring (not shown) to hold pressure roller I4I against platen 83. When lever I38 is rotated to the dotted line position I42, the cam portion I 31 acts upon arm I34 to depress link I35, thereby causing the levers H5 and I24 to rotate clockwise to move guide I22 and feeler II9 away from platen 83 simultaneouSly.

General operation The normal condition of the signal line is marking and hence the selector magnet I I is energized and the armature I2 is held attracted. Upon receipt of the start impulse of a code combination the selector magnet is de-energized and lever l3 upon being actuated clockwise by spring I5 causes screw head 35 to act through plunger 36 and levers 38 and 4| to release stop gate 46 to permit rotation of stop disc 52 and hence cam barrel 24, to effect, through levers 26, swords 22 and T-levers 3|, the setting of vanes 33 in accordance with the received code signal. At a predetermined instant in the cycle of rotation of cam drum 24, a cam 25 thereon operates a clutch release mechanism (not shown) on the main operating shaft 23 to initiate rotation of an operating cam assembly (not shown) a cam on which controls, through the printing bail, the operation of a function lever bail identified in Fig. 2 by the rod 59 for controlling the function levers, and another cam on which controls, through the function bail, a bail blade 76 for operating the function push bars; for example, line feed push bar 66.

Upon receipt of a tabulator signal (for vertical tabulation or multiple line feed) the vanes 33 are set characteristically in the manner described, and upon operation of the function lever bail 59 the vertical tabulator function lever 55 will be selected and rotated about pivot rod 56 by spring 51 to raise arm 6| whereby, through screw 62, multiarmed lever 64 is rocked counterclockwise to become latched by the spring biased latch arm 68. Arm 65 of lever 64 raises line feed push bar 66 to bring the shoulder I5 thereof into the path of function bail blade I6 preparatory to performing a series of line feed operations as hereinafter set forth. Arm 84. of lever 64 performs two functions; namely, the end thereof acts on contact spring 85 to open contact 86 in the operating circuit for the start magnet of the transmitting distributor to suspend transmission during vertical tabulation (assuming switch I00 to have been previously closed) and also, clockwise movement is imparted to bell crank 88 to cause link 02 and slidable member 94 to move leftwardly (Fig. 1), thereby causing arm 96 to rock latch lever 0| to unlatch stop gate 46 to permit disc 52 and cam drum 24 to rotate. Since member 94 is held in its leftward position as long as the plural armed lever 64 is latched up by latch 58, stop gate 46 will remain unlatched and cam drum 24 will rotate continuously. This constant rotation of cam drum 24 will, through its aforementioned control over the clutch release mechanism for the main operating cam assembly (not shown), cause the function bail comprising the function bail blade I6 to be operated repeatedly. Push bar 66, being held in the path of function bail blade I6, will also be operated repeatedly, and through levers I2, link 11, bell crank lever I8, pawl 8| and ratchet wheel 82, will cause platen 83 to be line fed successively. By this means and through the co-operation of sprocket feed pins I43 and pressure roller I4I, the sprocket feed paper, as illustrated in Fig. 3, is fed through the printer. It is important in this connection to point out that the function lever 55 responds only once to the vertical tabulator signal and in so doing causes the plural armed lever 64 to become latched up, and control of vertical tabulation thereafter is transferred to said lever 64. Since the normal condition of the signal line is marking, the line magnet I I will be energized, and during subsequent rotations of cam drum 24 the "letters or unshift combination, which is an all-marking code combination, will be set up, in response to which the unshift function lever will be selected, which is a nonprinting and nonspacing function and which has no effect upon vertical tabulation. Thus, only a single operation of the vertical tabulator function lever in response to the vertical tabulator code signal is assured.

The record material employed in connection with the present invention constitutes preferably (though not necessarily) sprocket feed paper, as indicated in Fig. 3, comprising a series of blank forms I44 of the same standard length, which may have preprinted headings. To govern the feeding of the forms into proper printing position following the completion of the message recorded on the preceding form, a control hole or perforation I45 (Fig. 3) is provided in each form I44. The hole I45 is so positioned on the form I44 so as to coincide with the sensing printing point. As previously indicated, themessages on each form I44 may contain different numbers of printed lines, and accordingly, before the first line of the next message may be printed, an additional feed must be imparted to the preceding message. This additional feed is initiated by the selection of the vertical tabulator function lever in response to the vertical tabulator code signal, as just described, and continues in response to repeated line feed operations until the control hole I45 is sensed by the feeler II9.

Line feed of the platen 83 is effected in the direction of the arrow (Fig. 1) upon each downward movement of the link 11. As bell crank lever I8 is actuated counterclockwise, pawl 8I operates ratchet wheel 82 in the usual manner to effect a line feed of one step, and the vertical arm of lever I8 strikes the depending arm I33 to impart clockwise movement to rock shaft I29, thereby lifting latch arm I28 out of latching engagement with arm I26 of plural armed lever II5. Spring I32 will then urge lever II5 counterclockwise to bring feeler I I 9 into contact with the underside of the paper I44. The movements of the elements may be so timed that the feeler Il9 will touch or sense the paper I44 during the rest period between successive line feed operations. With this arrangement, dragging of the sensing element upon the record material is avoided. If no hole I45 is positioned opposite feeler I I9, only a limited rotation of lever H5 will result, and arm III thereof will still block arm I0I, thus preventing shaft I02 from rotating clockwise sufiiciently to cause, through arm IN, the bar 98 from unlatching arm 68 from arm 61 of plural armed lever 64 to stop vertical tabulation."

When the line feed link TI is returned to its upward position, lug I04 acts, through arm IN, to impart counterclockwise movement to shaft I02, to impart like movement to lever I05, so that stud H3 or arm I08 thereof acts on arm II4 to return lever I I5 to its clockwise position, thereby permitting arm I26 to become again latched by latch arm I28.

If, when lever H5 is unlatched in response to a line feed operation, the feeler I I9 senses a control perforation I45 and passes therethrough, lever H5 is caused to rotate counterclockwise a greater amount than otherwise to remove arm I I I out of blocking relation with arm I01, thereupon spring I09 is enabled to rotate lever I05, and hence shaft I02 a sufli'cient amount to depress bar 98 and latch arm 68 an extent great enough to unlatch arm 61 of plural armed lever 64. Upon being thus unlatched, lever 64 returns to the position shown in Fig. 2, to restore contact 86 to its closed condition, thus resuming transmission; to drop push bar 66 out of the path of function bail blade I6, and to permit bell crank lever 88 to return to its counterclockwise position to free latch lever 4|, so that the latter responds to its spring 48 tolatch the stop gate 46 against movement, thereby preventing further rotation of cam drum 24. The vertical tabulating mechanism according to the present invention is thus restored to its unoperated condition in readiness for a subsequent vertical tabulating signal. In the embodiment of the invention just described, the amount of movement of arm I01 (when unblocked) to effect the unlatching of arm 68 is independent of the degree of movement of sensing arm ,I I9, thus increasing materially portion H9 when the first typing line is at the the margin of operation of the vertical tabulator,

Modification A modified form of page sensing mechanism is shown in Fig. 6 and contemplates the sensing of the control hole in the record material farther from the printing point and does not require grooving the platen for the feeler or stabber. In this form of the invention a line feed link lI (comparable to link 11, Fig. 1) is pivoted to one arm of a line feed bell crank lever I52, to the vertical arm of which is pivoted a pawl I53 which co-operates with a ratchet wheel I54 fixed to the platen I55. A bar I56 (comparable to bar 98, Fig. 1) controls a latch similar to latch 66 of the principal embodiment of the invention, and is pivoted to an arm I51 fixed to one end of a rock shaft I 58, to the other end of which is secured a sensing lever I59 carrying at its outer extremity a feeler portion I6 I. Lever I 59 is provided with an upstanding hook portion I62 which is engageable with a latch arm I63 pivoted at I64 to the platen carriage side frame I65. Lever I59 is also provided with a projection I66 to the end of which is fastened one end of a spring I61, the other end of which is attached to the latch arm I63. Spring I61 thus acts to biasjlever I59 clockwise and to urge latch I63 counterclockwise into latching relation with hook portion I62. Latch'arm I63 is provided with a projection I68 which co-operates with an arm I69 fixed to a rock shaft I1I. Also carried securely on shaft HI and positioned in co-operative relation with line feed bell crank I52 is a depending arm I12. A spring I13 attached to arm I69 tends to rotate shaft I1I normally in a counterclockwise direction. Fixed to shaft I58 is an arm I16 which engages lever I52.

The record material I14 of the form shown in Fig. 3 is fed between an apron or plate I15 and a guide plate I 16. At a point coincident with feeler I6I, plates I15 and I16 are perforated to permit the passage of said feeler therethrough when a control perforation similar to perforation I (Fig. 3) is found. The record material is directed around the platen I55, and engages the sprocket pins I11 in the usual manner.

Line feed of the platen I is achieved in the direction of the arrow (Fig. 6) upon each downward movement of link I5I. As line feed lever I52 is operated counterclockwise, pawl I53 acts upon ratchet wheel I54 in the usual manner to effect a line feed of one step, and the vertical arm of lever I52 strikes the depending arm I12 to impart clockwise movement to rock shaft I1I, thereby, through arm I69, swinging latch arm I63 out of latching engagement with sensing lever I59. Spring I61 will then urge lever I59 clockwise to bring feeler I6I into contact with the top side of the paper I14. If no hole I45 is positioned opposite feeler I6I, only a limited rotation of lever I59 will occur and arm I51 will be prevented from rotating sufficiently to cause, through bar I56, the unlatching of the plural armed lever similar to lever 64 (Figs. 1 and 2).

When the line feed link I5I is returned to its upper position, the lever I52 acts, through arm I16, to impart counterclockwise movement to shaft I58, to impart like movement to lever I59 thereby permitting lever I59 to become latched again by latch arm I63. If, when lever I59 is unlatched in response to a line feed operation, the feeler I6I senses or finds a control perforation I45 and passes therethrough, lever I59 is caused to rotate clockwise a greater amount than previously under the influence of spring I61, whereby shaft I58 is likewise rotated a sufficient amount to depress bar I56 an extent great enoughto unlatch arm 61 (for example) of plural armed lever 61 (Fig. 1), the efiect of which is as described in connection with the principal embodiment of the invention. It is understood that the invention is limited to the forms herein described, but embraces all forms which come within the scope of the appended claims.
